Genetic variation within and between populations of the asexual plant Puccinellia x phryganodes
Puccinellia x phryganodes (Trin.) Scriber and Merr is widely distributed in Arctic salt marshes. In North America the species, which is capable of extensive clonal growth, appears to be a sterile triploid (2n = 21) seed set has never been observed. Consequently it was predicted that the level of gen...
